Filter by:In a single-blind, crossover, randomized, controlled trial with 40 participants we aim to demonstrate superior anaesthetic efficacy of lidocaine-23%-tetracaine-7% (IMP2) gel over EMLA 5% cream (IMP1) at comparable safety in sharp wound debridement of chronic leg ulcers. This is a monocentric investigator initiated trial conducted in the University Hospital Zurich. In this longitudinal trial, participants receive a sequence of different treatments (treatments on different days) and therefore are randomly assigned to one of two treatment sequences. One-half of participants will first receive IMP1 (first treatment visit, randomized) and then IMP2 (second treatment visit, crossover); the other half of participants the reverse sequence (first treatment visit: IMP2, second treatment visit: IMP1). Primary Objective: We want to show that IMP 2 (lidocaine-23%-tetracaine-7% gel) is more effective in pain reduction than IMP 1 (EMLA® 5% cream) in sharp wound debridement.
The goal of this study is to test a new gelling fiber wound dressing with silver on patients with a venous leg ulcer Participants will be asked to wear the test dressing in a four weeks period (+/- 2 days) consisting of 6 study visits, and will have the dressing changed once pr. week at the research facility. The wound will be cleaned, assessed and photos will be uploaded to a digital software system.
Every year, 5 million people throughout Germany suffer from extensive, often chronic wounds. Cold plasma is an innovative therapeutic approach in the treatment of these persistent tissue defects. However, previous therapy options with cold plasma are very time-consuming, especially with increasing wound area, and are also strongly dependent on the skill of the practitioner. This study investigates the effectiveness of a system for reproducible application of cold plasma on larger areas and observes the effect of a 4-week additional plasma treatment on wound healing of large chronic wounds. The patient-related benefit of such an additional treatment will also be evaluated. Both study arms will receive guideline-based wound therapy, which is the current gold standard.
A randomised controlled investigation comparing the clinical performance and cost effectiveness of Biatain® Silicone with Standard of Care dressing including filler in chronic wounds (CP351 - BISIL Study) This study (BISIL) will compare the Biatain® Silicone dressing to commonly used wound care products (AQUACEL®EXTRATM Hydrofiber® Dressing used with Mepilex® Border). The study will recruit in total 100 adult subjects with a venous leg ulcer or a diabetic foot ulcer no deeper than 2cm. Only ulcers with a duration of at least 8 weeks but no longer than a year will be included. The study will be a randomised controlled trial where half of the participants will use Biatain® Silicone and half will use the comparator for 4 weeks. Each participant will be in the study for 4-5 weeks during which there will be a weekly visit with the study team to complete the study assessments and change the dressing. The study will run for approximately one year, starting in January 2023.
Evaluation of the efficacy (wound epithelialization and time to closure) and tolerance (emergence and nature of adverse event) of the new URGO AWC_008 and URGO AWC_022 dressings in local management of acute and chronic wounds at risk of local infection or with clinical signs of local infection
Single-centre clinical study investigating the safety and tolerability of randomised, double-blinded, placebo-controlled ascending single doses of topically applied SoftOx Biofilm Eradicator (SBE) in patients with chronic leg wounds and of open-label once daily, twice daily, and thrice daily dosing of topically applied SBE for five days in patients with chronic leg wounds. The primary objective of the study is to assess the safety and tolerability of single and multiple doses of topically applied SBE in patients with chronic leg wounds. A secondary objective of the study is to assess changes in bacterial burden in the leg wound after treatment with SBE.
EVLA is used in in treating refluxing veins, commonly the GSV. The tip of catheter is usually placed 2-2.5 cm distal to the sapheno-femoral junction. This technique theoretically provides the lowest risk for endothermal heat-induced thrombosis (EHIT). In the present study we aimed to evaluate the zero-distance technique (the kissing technique) compared to 2-cm distance from SFJ valve in ablating incompetent GSV.
This study seeks to demonstrate the performance of Negative Pressure Wound Therapy on chronic wounds such as diabetic foot ulcers and venous leg ulcers.
Study Summary A leg ulcer is a long-lasting (chronic) sore that takes more than two weeks to heal. The majority of leg ulcers are caused either by problems with the veins in the legs; these are called 'venous leg ulcers' (VLU), or a combination of both venous and arterial disease which affects the veins and arteries in the leg; these are called 'mixed aetiology ulcers'(MLU). Venous and mixed aetiology leg ulcers are usually treated by applying a simple non-stick dressing to the ulcer with a firm compression bandage applied on top. These bandages are designed to squeeze the legs and encourage blood flow towards the heart. Before this treatment starts, a patient may undergo tests to check the flow of blood in the leg arteries is adequate. This ensures that compression bandaging can be safely applied to assist wound healing without compromising arterial blood flow. Most venous and mixed aetiology leg ulcers heal within three to four months if they're treated by a healthcare professional trained in compression therapy for leg ulcers. However, some ulcers can be more problematic and may persist for many months or even years despite being treated with the gold standard treatment of compression bandages. We therefore need to find more ways of helping these problematic ulcers to heal. Intermittent Pneumatic Compression (or IPC) is another way of compressing legs to try and improve the circulation. IPC consists of a sleeve or garment which is applied to the leg. The sleeve is connected to a pump which gently inflates and then deflates it to squeeze the leg in a massage like manner. The IPCOTT study aims to find out if a new IPC device, known as the WoundExpress can help to heal leg ulcers. The WoundExpress has a sleeve that patients put around the thigh, like the one applied to the arm when people have their blood pressure taken. Users need to be either sitting with their legs raised or lying down when using the device. Pressing the 'start' button on the pump causes the sleeve to automatically inflate with air for 2 minutes, until it reaches a pressure of 60 mm/Hg (this is low compared to the pressure used when measuring blood pressure; most patients find it very gentle and comfortable). After the 2-minute inflation, the sleeve will automatically deflate for another 2 minutes, where no compression is applied to the thigh. These 4-minute inflation and deflation cycles will repeat whilst the device is in use. People who take part in the study will be randomly allocated to Group A or Group B. Patients in Group A will continue to receive their usual wound care but will also be provided with a WoundExpress device to use for 2 hours per day for a 16-week period. Patients in Group B will continue to receive their standard wound treatment only for the 16-week study period (patients in Group B will be offered the chance to use the WoundExpress device for a 16-week period after the study has ended). All patients taking part in the study will be asked to attend their Wound Clinic for a study review once every two weeks during the study period. At these visits, a research nurse will take measurements and photographs of the ulcer(s) and participants will also be asked some questions about how they have been feeling since using the device. Patients who have been given a WoundExpress device will also be asked to keep a diary recording when they use the device and how they found it. When the study is complete, results will be analyzed to find out if there was any difference in ulcer healing rates between Group A and Group B.
The aim of this post market clinical follow up (PMCF) study is to confirm the performance of Suprasorb® A + Ag wound dressing and rope, to collect safety data regarding expected adverse events and to detect potential unexpected adverse events associated with use of Suprasorb® A + Ag wound dressing and rope within the certified indications and under the conditions of routine use.
